Superboy Season 4 Episode 12

To Be Human (2)

Bizarro now has a normal human appearance and is calling himself Bill Zarro. He has no super-powers in this form. He is working with Dr. Lynn to improve his mental skills when Chaos interrupts a TV broadcast. He announces that he has Superboy and will throw him off the highest building in Capitol City at midnight. Dr. Lynn recognizes Chaos. She says he was once a brilliant scientist, but a laboratory accident left him disfigured and now he blames the world for his problems. Bill Zarro now has to make a choice. He can be reverted back to the way he was before the process was performed. He can become ""Bizarro"" again, but the process cannot be reversed again once this is done.
